Did you make this instructable?

This type of system will do the job. You may need multiple stages due to the head pressures wencountered. The making of the wind pumps is easy. A tower, some pully wheels, the belts, an old motorcycle cylinder as the pump, a one way water valve, and some welding. Hope this helps. Best, Smitty

I've pondered the same issue. My hill isn't 200 feet high, which is daunting to me and would clearly seem to require a pump, but I have thought about designing an aqueduct sort of thing to attach to my rain gutters on the roof . In my mind's eye, the aqueduct would be supported high over the garden with a slightly downward slope until it bumps into the hill. I would have a cistern or rain barrels or even a pond at that point on the hill to receive the water, and then irrigate downhill to the garden as suggested. I haven't thought through how to construct the adqueduct or how to attach it to the gutters or how to support it up the hill, but I welcome suggestions!
